Rental of transformer stations

SONN certified rental of transformer stations IEC 62271-202

To guarantee our clients the usual SONN safety levels even during temporary rental projects, we were the first provider to test our container transformer stations in an external test laboratory for compliance with the new IEC 62271-202 standard. SONN transformer stations are also checked for compliance with the internal arc classification according to IAC A and B at 20 kA, to ensure a high level of public safety and the safety of switching staff.

By passing the tests, we demonstrated that during time-limited projects, such as construction sites, tunnel construction, drilling or conversions, there will be no compromising of quality and safety.

Our transformer stations are rented following adjustment and testing based on the requirements of the client or grid operator. We take care of the technical clarification of the grid operator (DNO) specifications, documentation, and shipping the MV-converter, development and testing as well as the delivery and installation of the rental transformer station with our own heavy-duty vehicles. We create the operating and control earth, including earth measurement in accordance with the regulations. After the joint commissioning, we perform the maintenance during the rental period.
